Patent IT-1188273-B (IT)
Title: Moulded case circuit breaker with reduced contact mounts
Inventor: KLEIN KEITH WILLIAM
IPC: H01H/
Filed: 1986-01-17
Granted: 1988-01-07
Abstract: The circuit breaker has a shortened contact separation distance upon manual operation to reduce the stresses imposed upon the breaker operating mechanism when the breaker is manually operated to open or close the contacts. A camming surface is provided on the cradle operator to provide a stop for the toggle pin both upon opening as well as upon closing the contacts. Decreased separation occurs between the contacts upon manual operation. The decreased stresses on the mechanism correspondingly allows for a reduction in the material strength and mass of the breaker flexible connectors, operating springs, and contacts.

Title: Single use syringe with device protecting against accidental puncture after use
Inventor: PEROTTI FRANCO
IPC: A61M/
Filed: 1990-01-30
Granted: 1993-06-23
Abstract: The present invention refers to a single use syringe with device protecting against accidental puncture after use. The syringe consists of a syringe body which internally defines a containment cavity of the liquid to inject and which lodges a sliding plunger moving along the cavity. The syringe is equipped with a needle associated in a sliding manner to the body of the syringe and which is held, in position of engagement, by fixation elements. Said fixation elements can be disactivated as desired, upon termination of the injection, to induce passage of the needle from an engaged position to a protective position, in which the needle is completely lodged in the syringe body, preventing thereby, the danger of accidental puncture after its use.

Granted: 1987-09-23
Abstract: A peptide has been isolated and made comprising an epitope of a circumsporozoite protein of a member of the genus Plasmodium. The peptide is useful in development of a vaccine against malaria and it can be prepared by recombinant DNA techniques in the form of a fusion protein. DNA fragments have been produced coding for such peptide and microorganisms have been transformed expressing said peptide. An immunodominant region has been identified within such a peptide and a shorter peptide analog has been prepared, the analog displaying immunoreactivity with a monoclonal antibody to the peptide substantially equivalent to that of the peptide itself.

Title: Max. speed and braking system for locomotives - optimises drive and braking effort with additional control sequence
IPC: B61L/
Filed: 1977-07-13
Granted: 1989-11-22
Abstract: The max. speed and economy braking system for railway locomotives allows the train to maintain higher speed - up to the max. allowable - but with reduced braking effort required to come to rest at a given point. The speed/braking curve established by the additional control circuits has two deceleration and two braking curves. at max. speed, a point is reached on the coasting curve (ALK1) when drive is removed until the braking curve is reached (K6). Speed is reduced to a target speed level (P4) and this is maintained until a point on the second coasting curve is reached (K7) (ALK2). Drive is disengaged until a point is reached on the second braking curve (B2) (K9). Braking is then maintained by the controller according to the braking curve until the stopping point (p6) is reached.
Patent IT-1147644-B (IT)
Inventor: GRECSEK JOHN JEROME
IPC: C11D7/00
Filed: 1982-02-25
Granted: 1986-11-19
Abstract: Free flowing spray dried beads which are useful as a detergent or for the manufacture of a particulate built synthetic nonionic organic detergent composition include water softening aluminosilicate (such as a zeolite), bentonite and water soluble builder, and may also include water soluble synthetic organic detergent and a small proportion of water soluble silicate, although such silicate is preferably omitted. The beads can be made to be of a bulk density within a broad range, and the bulk density may be varied by control of the bead formula and by modification of spray drying conditions. The base beads and detergent compositions formulated with them are of reduced aluminosilicate deposition characteristics, due to the presence of bentonite and the absence of or presence of only a low content of water soluble silicate, with the bead composition being maintained within given ranges. The moisture content of the beads will be such as to maintain at least 2% and preferably 3% or 4% or more of moisture in the bentonite so that its normal swelling power is retained, because the swelling of the bentonite is considered to be important in dispersing the beads in wash water and also, even more importantly, in helping to prevent aluminosilicate agglomeration and objectionable deposition thereof on materials washed, and in helping to break up any minor proportion of such agglomerates which might be formed.

Title: Heavy water prodn. without foam formation - by preventing the formation of hydrate in the cold tower due to the presence of liq. hydrogen sulphide
IPC: C01B/
Filed: 1976-12-14
Granted: 1989-03-31
Abstract: Heavy water is produced using an H2S-H2O isotope exchange of Gridler sulphide type in which H2S is formed as a liq. and acts as antifoaming agent. The sepn. stage consists of a hot tower and a cold tower contg. isotope exchange units in the shape of sieve plates through which H2S gas and H2O liq. pass in countercurrent. Liq. H2S may be formed in the cold tower by adjusting the pressure in the cold tower, or may be injected into the cold tower to prevent foaming on the sieve plates. The pressure of liq. H2S in the cold tower prevents hydrate formation which causes foaming. The higher pressure in the cold tower leads to a higher pressure in the hot tower and facilitates operation at higher temp., which increases the efficiency of extn. while a more even temp. distribution is achieved in the cold tower.
